The aggregate used in road construction begins degrading integrity of said roadway when pieces begin exceeding 23.5 millimeters in diameter. Any pieces smaller than 23.5mm in diameter are fine. The recently delivered load of aggregate being used has a 19mm mean and 5.5mm standard deviation. What is the Z value to two decimal places?
